Managing PHP Versions and Extensions Per Account
Different applications may require different PHP versions or modules. Version changes should be controlled and documented because they can affect compatibility quickly.
Change Management
- Review application requirements before changing the active version.
- Enable only the extensions required by the application or service.
- Test major version upgrades in a lower-risk environment when possible.
- Keep a rollback path available if a change causes unexpected errors.
Common Failure Pattern
Many post-upgrade issues come from deprecated functions or missing extensions rather than the version change alone. Error logs usually identify the real dependency gap faster than trial and error.
